The trampolines use PC-relative addressing to load their context from the config page, and so it is possible -to allocate as many of these trampolines tables as you have memory space. - -Note that this implementation is *experimental* and has seen very limited testing. - -A build-ios.sh script is provided to configure and build an iOS library; you may need to edit the SDK settings in the script. |
